Installation Place
Requirements
Before installing the appliance, check the following
information to make sure that the appliance
should be installed in a correct place.
Flooring
• To minimize noise and vibration, install the
washer on a level, solidly constructed floor
capable of supporting the appliance without
flexing or bouncing.

more than
2.5 cm
from front to back or side to
side.
• Installing on carpeting and soft tile surfaces is
not recommended.
• Never install the appliance on a platform or
weakly supported structure.
Floor Installation
To ensure sufficient clearance for water inlet hoses,
drain hose and airflow, allow minimum clearances
of at least
2.5 cm
at the sides and
10 cm
behind the
appliance. Be sure to allow for wall, door, or floor
moldings that may increase the required
clearances.

Closet Ventilation Requirements
Closets with doors must have both an upper and
lower vent to prevent heat and moisture buildup in
the closet. One upper vent opening with a
minimum opening of 310 cm
2
must be installed no
lower than 6 feet above the floor. One lower vent
opening with a minimum opening of 155 cm
2
must
be installed no more than one foot above the floor.
Install vent grills in the door or cut down the door

least 20 mm thickness of rubber caps
a
under
each adjusting foot of the appliance, secured to
at least two floor beams with screws.
• If possible, install the appliance in one of the
corners of the room, where the floor is more
stable.
• Fit the rubber cups to reduce vibration.
CAUTION
• If the appliance is installed on the unstable floor
(e.g. wooden floor), the warranty does not cover
any damages and cost occurred due to the
installation on the unstable floor.
NOTE
• You can purchase rubber cups (part No.
MJB65174401, MJB65174501
) from the LG
